Product detailed description

LAZENA® H2-300M – Hydrogen & Oxygen Inhalation Generator
Breathe ultra-pure molecular hydrogen (H2) and oxygen (O2) in a comfortable home routine. Advanced SPE/PEM technology with titanium electrodes generates stable, high-purity gases from distilled water for daily wellness, relaxation, and recovery support.
Why Hydrogen Inhalation?
Inhalation is the most direct way to enjoy molecular hydrogen — a tiny, fast-diffusing molecule valued for its antioxidant balance support. Hydrogen is known for selectively targeting unwanted oxidative stress while respecting the body’s natural signaling. Add a simple breathing session to your day and build a routine that feels premium, effortless, and consistent. Learn more in our molecular hydrogen article.
Antioxidant Balance Support
Helps support the body’s response to oxidative stress from modern lifestyle and training.
Calm Breathing Routine
A comfortable session that fits morning focus, evening wind-down, or post-work reset.
Recovery & Regeneration
